all,</FONT></SPAN></DIV>

<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>I have a curious
problem - I try to run a fine grid (with spatial resolution 1.0x1.0
km) using initial-nudging data from grid 3 (nestdown) of the
finished 3-grid run (27-9-3 km spatial
configuration).</FONT></SPAN></DIV>

<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>But for the
particular place of New Zealand (and only for it and I don't know why!) in the
middle of the South Island WRF (fine grid 1 separate run) stops reaching
radiation calculation block and gives "fragmentation error". Initially I
used 'radt=27' (as the spatial resolution of a mother grid for 3-grid run
was 27 km).</FONT></SPAN></DIV>
<DIV><SPAN class=855192500-23052008><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>I tried to play
with radiation parameters and radt value and made WRF working
for radt=1 and time_step=0.5 of a second. </FONT></SPAN></DIV>
<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>But this
configuration is useless as WRF runs 1 hour about 45 minutes and I need to
run a year!</FONT></SPAN></DIV>

<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>I
didn't collide in such a problem before.</FONT></SPAN></DIV>
<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>Could it be a
problem with IBM P575 (I work at) level of optimisation or some
another P575 (AIX) stipulation of the maximum number of
the iterations?</FONT></SPAN></DIV>

<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>I
had a problem several years ago that reminds me this one.
</FONT></SPAN><SPAN class=855192500-23052008><FONT face=Arial size=2>I
was trying to run MM5 on Unix workstation (Solaris) and MM5
stoped at the beginning after several time steps: only a command "-fast
-nodepend" helped me to run MM5 normally. </FONT></SPAN></DIV>

<DIV><SPAN class=855192500-23052008><FONT face=Arial size=2>Any suggestions are
highly appreciable.</FONT></SPAN></DIV>
